PDXPUG: March meeting in two weeks

When: 6-8pm Thursday Mar 17, 2016
Where: Iovation
Who: Josh Berkus
What: Big Data on Pg 9.5

PostgreSQL 9.5, released in January, is full of tasty goodness for big data folks: UPSERT, new aggregation types, OLAP support, new Foreign Data Wrapper functionality, BRIN indexes, and more. Josh Berkus will give us a rundown of these features, with multiple demos.

Josh Berkus is a member of the PostgreSQL Core Team, and works at Red Hat where he manages the Project Atomic community. Containers, containers, containers! Which is appropriate, since he’s also a potter.

PDXPUG: February meeting in two weeks

When: 6-8pm Thursday Feb 18, 2016
Where: Iovation
Who: Jason Owen
What: Incremental Schema Discovery via JSON Wrangling

Over the last few releases, Postgres has added and expanded support for storing and querying JSON documents. While the simplicity and flexibility of storing free-form data can be appealing, frequently what’s stored is actually fairly structured. Using data from the GitHub Archive, Jason will show how easy it is to load JSON into Postgres, demonstrate some fairly mechanical schema refactorings to extract structure from JSON data, and then compare the resulting normalized tables with the original, with the documentation, and with the data set loaded into Google BigQuery.

Jason has been using Postgres in earnest for two years now. While he’s worn the DBA hat as a full stack engineer from time to time, he is primarily a developer. He works at Tripwire and is an alumnus of Portland State University. Sometimes he says things online as @jasonaowen.

PDXPUG: January meeting

NOTE: This month’s meeting is one week earlier than our usual schedule, so we don’t conflict with SCALE.

When: 6-8pm Thursday January 14, 2016
Where: Iovation
Who: Gabrielle Roth
What: RDS Postgres

Amazon integrated Postgres into their general Relational Database Services (RDS) offerings July 1, 2014. RDS offers automatic failover, scalability, and easy configuration, plus Amazon handles all the patching and most of the upgrades for you! Their SDK supports many languages and includes a robust CLI, if you want to automate management of your deployments. They also support several popular Postgres extensions.

Of course, since it’s a managed service, you can’t do everything you might expect or want to. We’ll discuss the fun and quirky features I’ve discovered in a year and a half of working with production RDS deployments. Come find out what it’s like to use RDS Postgres day-to-day.

(This is an updated version of my talk from last year. )

Gabrielle has been using Postgres since sometime in the version 7s and thinks that the best part of using Open Source software is the culture of sharing knowledge. She co-leads PDXPUG, the Portland PostgreSQL Users’ Group. Gabrielle’s current areas of interest are monitoring, benchmarking, and writing freaky SQL.

PDXPUG October meeting in two weeks

When: 6-8pm Thursday October 15, 2015
Where: Iovation
Who: Gavin McQuillan
What: Sharded Postgres with PLProxy

Data of Future Past: Postgres as Distributed Online Processing Analytics Engine

Postgres has long been a great analysis tool, but as organizations seek to decentralize their data, it’s overlooked for other solutions. Maybe this doesn’t need to be the case. Using a novel combination of tools, old and new, Postgres can also decentralize its data. We can maintain the immensely powerful interface that we love, while meeting (or exceeding) throughput decentralized datastores provide. In this talk we see how this is possible using Foreign Data Wrappers (PLProxy) and HyperLogLog (Postgres-HLL) extensions, detailing benefits and constraints to this method. We explore a reimplementation of a complex Online Processing Analytics hypercube in Hbase with Postgres and measure its effectiveness, throughput, latency, and cost savings.

Gavin is a longtime PostgreSQL enthusiast, specializing in building automation and analytics solutions, distributed systems, scaling and securing web applications. His experience includes Google SRE, software development and leading teams in young technology startups. He lives in Portland with his family, bicycles, and hand planes.
